平煤十三矿构造煤发育特点与分布规律

Characteristics and distribution regularity of tectonic coal development in No.13 Coal Mine of Pingdingshan Tian'an Coal Industry Co.,Ltd.

构造煤研究是开展瓦斯地质工作的重要内容,其对煤与瓦斯突出预测至关重要。采用煤壁观测和钻孔取心分析的方法,对平煤十三矿构造煤发育和分布特点进行梳理总结,构造煤具有2~3层软弱分层,层状、似层状分布,软煤类型以粉状和糜棱为主,主要受构造的落差、走向、断层性质控制。此外,构造煤发育程度和厚度还与倾角、褶皱、夹矸等多种地质因素有关。采用煤壁观测记录和钻孔取心方法对其进行调查研究,初步掌握了其特征和分布规律,为今后安全生产提供技术参考。

Tectonic coal research was an important content of the gas geological work,and it was essential to the prediction of coal and gas outburst,therefore the coal wall observation and analysis of drilling core method,to 13 in the development and distribution characteristics of mine tectonic coal comb summary,tectonic coal was 2~3 layers of weak layer,layer,layer distribution,type of soft coal was given priority to with powder and mylonite.Mainly controlled by tectonic disparity,direction,fault properties.In addition,the thickness of tectonic coal development degree and also the obliquity,fold,dirt band and other relevant geological phenomena.Based on the coal wall observation records and drilling core method carries on the investigation and study,a preliminary to the characteristics and distribution regulation of master,to provide technical reference for the safety in production.
